Ellis, 27, was also reportedly contacted by Chicago, Phoenix, Denver and New York. Dallas and Atlanta were also mentioned as possible destinations before the free agent period began at midnight Eastern on Sunday.

The eight-year pro opted out of the final year of a contract that would have paid him $11 million this season. He averaged 19.2 points and 6.0 assists for a Milwaukee team that was bounced out of the first round by Miami.

Ellis ranks among the more explosive scorers in the league, but without much efficiency. He has averaged 19.4 points on 16.4 shots during his career, and is just a 31.8-percent 3-point shooter.

But he can also fill both guard positions, which is a possible need for the Spurs after injuries and fatigue to Tony Parker late in the Finals forced Manu Ginobili to serve as the de facto point guard.
